' Application filed September 27, 1926. Serial No. 138072.

small quantities of liquid such as lubricating wall of the casing and at its opposite end in a oil which may be purchased by a single'coin; and 111 whlch simple means 1s provided for varylng the amount purchased by'such coin,

or in other words varying the purchasing power of the coin inserted in the machine, and

it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained. p. i

Fig. 1 is a view partially in section and partially in elevation of my device applied to an oil dispensing tank. 7 l i Fig. 2 is an enlarged sectional detail of the maj or portion'of my mechanism. Fig 3 is a plan view. Fig. e? is a sectional detail.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates a tank connected in the usual manner to the main supply tank and provided with a piston 2 and. piston rod 3 operating therein. e indicates the inlet pipe for feeding the oil into the tank 1 and 5 the outlet pipe, such pipes being suitably'arranged and valved according to connnon practice. 6 is a rack formed integral with or suitably connectedto therod 3. 7 is a casing mounted upon suitable supports such as indicated at 8. The casing 7 is provided in its front wall with an orifice 9 provided with a hinged cover lOwhich is firmly locked in position by a. hasp and padlock such as indicated at 11.

12 is a shaft extending transverselythrough the casing and journalled at one end inthe suitable journal bracket 13 mounted to extend centrally of the opening 9. 14 is a slide bar v provided with a rectangular orifice 15 through which the shaft 12 extends so as to perntit the j .arm 42 in the direction of arroi'v, see Figure free horizontal longitudinal moven ent of the slide bar 14:. 16 18 a disc secured to the shaft 12 and provided around its outer periphery with angular teeth 17 18 is a-spiral groove formed in the face of the disc lfiand provided at suitable distances apart with small orifices 19 formed in the face of the groove and spaced apart and opposite each of which are quantity of the orifices 19. 21 is a coin receivingslot' in the upper wall ofthe casing 7. 22 is a "the operation of the same. 1 1

lever pi-votally mounted at its upper endbetweenavalls 23 depending from each side of the slot 21. 2-1 is a slide bar slidably held Within a slideway 25 and provided at its outer end with a depending portion provided with a pin 27 extending into the groove 18. The opposite end of the slide bar 2d ispivotally connected to the lower end of the lever 22 as indicated. at 2s. f a

29 is apressure spring forcing the lever nward for a purpose which will hereinafter appear. v f

30 is a detent pivoted at 31 between the walls 23, the upper portion above its pivot point entending into the path of the coin inserted through the slot 21 so that the distance betwee'n'such upper end and the opposing portion of the lever 22 is less than the diameter of the inserted coin. The lower end of the detcnt 30 is provided with a tail piece '32. 33 is a lever mounted centrally of its length upon the wallof the casing 7 as indicated at 34. The upper end of the'lev-er is pivotally connected with a tail piece 32 as indicated at 35 and at its lower end to the slide bar 14 as indicated 'ati'id 39 is'a springbearinfr against the lower por tion of the 1ever33 below its pivot 84; 40 and 41 are spring pressed latch dogs adapted to alternately engage with theteeth -17 of the disc 16. 412 is the operating crank arm secured to the shaft 12. 43 is a gear also secured tothc shaft 12 and meshing with the tceth'of the tion 26 of the slide bar 241 is provided with a vertical slot in which is mounted a slide piece 44 upon which the pin 27is mounted.

Having described the principal parts involved in my invention I will hricny desc *ibe The crank shaft 12fis rotated by the crank 2. By thism'cans the disclfi is rotated in corresponding direction until the pin 27 luu reaches the opposite end o'fthegroovc 18; that I is the outer end of thegroovelv Simultaneous 1y with this operation the gear 43 in mesh with the teeth of the were carriesthe rack in a downward direction so'that the oil containeiil Withrn'the tank l'below the p ston 2 is forced amount of gasoline to be soldlforthe coin in through the piston valve 2 ahovethe piston; The pin 20 has been previously setiu one of, i the small orifices 19 opposite the indicating serted by the purchaser in the slot 21. setting of this pini20 of course is performed by the vendor at the beginning of each days opposinginwardly projecting ends of the de-:

tent 30. The spring 29 is relatively a stronglever 22 is held from movement andthe detent 30 swung outward from the dotted line. position to the full line position shown in the.

er. spring than the spring 39 and therefore when a co n s inserted as above described the drawing. By this means the lever 33 is'swung on its pivot 34 moving the slide bar 14L from the dotted line position to the full line position shown thereby carrying the spring latch 40 out of engagement with the teeth lTandi the spring latch 41 into engagement with the teeth. V v c I WVhen this operation is performed the operatorturns the crank arm 42 in the opposite direction to arrow, the engaged latch dog 41 permitting of this movement. By this operation the disc 16 is also turned in the reverse direction to arrow carrying the pin 20 into engagement with the pin 27 and thereby forcing the pin horizontally in the direction of arrow. and carrying the slide barj24 in a corresponding direction so as toicalry the lever 22 out of engagement with the coin, that is in thedotted position shown allowing the coin to drop and pass into the till. The engagement of the pin 20 withthepin 27 by limiting the rotation'of the disc 16 also limits the distance to which rection thereby limiting the upward movement of the piston 2 to discharge a quantity corresponding to that to which the-pin 20 has been set for. Whenthe quantityis to be varied-all the vendor has to do is to open the cover 10 and remove the 'pin20 fromits Lorifice and insert it in anyone ofthe other orlfices accordingto the quantity of-oilder,

sired to be sold. From this description it will be seen that I have devised a very simpleiforrnof dispensing apparatus which will dispense any given;

quantity of oil which is to besold fora coin inserted inthe' machine-according to the market value of the oil at any given day or in accordance with the-purchasing power ofthe coin for that particular day. i p v What I claim as my invention is theoperating shaft'of'the dispenser, of a cas-' ing'having-a coin slot and into which the aforesaid shaftextends', a disc secured to the shaft within thecasing, a stop adjustable ci re esasse from rotation'in the dispensing direction and permitting the rotation in the reverse direction, means operated; by the nsertlon of a coin in the coin slot for releasing such locking 2.
